It does not take the tandems identified as type CTL which have a hook to hold them into the correct location in the panel. The QO2020C, store sku 577006, ($56.26 ouch) should fit in the allowed locations. You are better off buying a bigger panel to start with since regular breakers would be cheaper and the install safer.
Hello Jacob, No, you need to remove the Knockouts, Regards, Schneider Electric Customer Care.
Hello Peter, In order to use it as a sub-panel (And separate the neutral and the ground) you need to remove the green bonding screw and add the ground bar to the QO124L125PGC. Regards.
Hello Tony, The NEMA 1 (indoor) CONVERTIBLE Mains (Like the QO130L200PGC), can be bottom fed by rotating the complete load center and cover. This will NOT cause the labeling to be "upside down", it will just start the circuit counting at the bottom of the cover where the Mains is located, but it will read appropriately.
Hello Nick, The QO load center has a Tin Plated Copper bus bars and for the neutral bar All load centers have aluminum neutrals as standard. Copper is not an option. And the ground bars are are made of tin plated Aluminum. Regards, Schneider Electric Customer Care
Hello Joe, If you already installed (2) single pole breakers, you have room for other (22) single pole breakers or (11) double pole breakers. Regards.
Hello Joe, Yes, you can use aluminium or copper wire. Regards.
Hello Baker, Yes you can convert this panel. Regards. Schneider Electric Customer Care.
Main buss bars are good for 125 amps, so proper 100 amp plug on breaker should work fine if all wire sizes are right. Only problem might be bending wire to fit into breaker.
